1 Report from the Kennel Club/ British Small Animal Veterinary Association Scientific Committee Summary results of the Purebred Dog Health Survey for the Grand Bleu de Gascoigne breed Warning: The results of this survey and particularly the breed-specific analyses should be interpreted with caution. The overall response rate was only 24% with breed-specific response rates from 4.5% to 64.7%.

2 The Grand Bleu de Gascoigne breed A total of 21 forms were sent out and 7 were returned, representing 14 live dogs. This breed had a 33.3% response rate (7/21) and it represented 0.05% of all returns (7/13,741). Mortality data A total of 6 deaths were reported and this represents 0.04% of all deaths reported in the survey (6/15,881). The median age at death for the Grand Bleu de Gascoigne breed was 4 years and 7 months (min = 2 years and 6 months, max = 10 years and 1 month) and this was lower than the overall median of 11 years and 3 months (Figure 1). Table 1 shows the causes of death for the Grand Bleu de Gascoigne breed. Age at death is presented for the most common causes of death (Figure 2). Table 1.

The dashed line ( ) is the overall median age at death for all dogs in the survey and the dotted line (----) is the overall median age of death for the Grand Bleu de Gascoigne breed. The solid line within each grey box represents the median age at death from the condition. Morbidity data The median current age of the 14 live dogs with a reported age was 4 years and 7 months (min=3 months, max=7 years, Figure 3). Health information was reported for 14 live dogs of which 9 (64%) were healthy and 5 (36%) had at least one reported health condition, resulting in a total of 10 reported conditions with a median of 2 conditions/dog (min=1, max=3). The median current age of all healthy dogs with a reported age (N=9) was 4 years (min=3 months, max=7 years). The distribution of gender and neuter status is shown in Table 2. The median current age of all dogs with one or more disease conditions and a reported age (N=5) was 4 years and 7 months (min=3 years and 2 months, max=7 years). The median age at diagnosis for all disease occurrences with a reported age at diagnosis (N=10) was 1 year and 10 months (min= 8 months, max= 6 years and 11 months, Figure 4). Table 3 shows the disease conditions for the Grand Bleu de Gascoigne breed. Age at diagnosis is presented for the most common disease conditions (Figure 5). 3
